Global Hopf Bifurcation Analysis for an Avian Influenza Virus Propagation Model with Nonlinear Incidence Rate and Delay

Abstract and Applied Analysis, 2014
The paper investigated an avian influenza virus propagation model with nonlinear incidence rate and delay based on SIR epidemic model. We regard delay as bifurcating parameter to study the dynamical behaviors.

一类具有临时免疫的时滞蠕虫传播模型的Hopf分支(Delay induced Hopf bifurcation in a worm propagation model with partial immunization)

Zhejiang Daxue xuebao. Lixue ban, 2016
This paper is devoted to Hopf bifurcation of a delayed SVEIR model with partial immunization that describes worms propagation on internet. Sufficient conditions for existence of Hopf bifurcation are obtained by considering the latent period time delay of

Global existence of periodic solutions in a simplified four-neuron BAM neural network model with multiple delays

Discrete Dynamics in Nature and Society, 2006
We consider a simplified bidirectional associated memory (BAM) neural network model with four neurons and multiple time delays. The global existence of periodic solutions bifurcating from Hopf bifurcations is investigated by applying the global Hopf ...

Degenerate Hopf bifurcation in a Leslie–Gower predator–prey model with predator harvest

Advances in Difference Equations, 2020
In this paper, we investigate the degenerate Hopf bifurcation of a Leslie–Gower predator–prey system with predator harvest. The known work discussed the Hopf bifurcation of this system when the first Lyapunov number does not vanish and gave an example of

Turing–Hopf bifurcation of a ratio-dependent predator-prey model with diffusion

Advances in Difference Equations, 2019
In this paper, the Turing–Hopf bifurcation of a ratio-dependent predator-prey model with diffusion and Neumann boundary condition is considered. Firstly, we present a kind of double parameters selection method, which can be used to analyze the Turing ...

Population Dynamic Study of Prey-Predator Interactions with Weak Allee Effect, Fear Effect, and Delay

Journal of Mathematics, 2022
In this study, a predator-prey model with the Allee effect and fear effect is established. We use the comparison principle to prove boundedness. The zero equilibrium point and nonzero equilibrium point of the model are calculated, and the local stability
